Maybe you should change your line of work. If you're that unhappy about what you do in spite of the fact that what you do is orders of magnitude more important than the next move-fast-and-break-things-advertising-driven-unicorn then that suggests to me that you should let someone else take over who does derive happiness from it and you get yours from a faster paced environment.
Personally, you couldn't pay me enough to do the latter and I'd be more than happy to do the former (but I'm not exactly looking for a job).
